Steel bar grating is manufactured through the forged welding process, which consists in welding steel cross rods to perpendicular and equidistant bearing bars. It goes through cutting, opening, edging and other process. We produce three kinds of steel gratings, they are Plain style steel grating, Serrated style steel grating and I bar type steel grating. The product feature of high strength, light structure, high bearing, convenience for loading and other properties. The hot dipped zinc coating gives the product excellent anti-corrosion.
We also can design and manufacture steel grating as per client’s requirements.
